[0017] like Figures 1 to 3 As shown, a ceramic heating element for water heating includes an upper ceramic layer 1, a lower ceramic layer 2, and a tungsten paste heating circuit 3 printed on opposite sides of the upper ceramic layer 1 and the lower ceramic layer 2. The upper ceramic layer 1 has a plurality of first spherical protrusions 101 integrally formed on its upper side in a rectangular array. The outer side of the spherical protrusions is printed with a tungsten paste heating layer. The first spherical protrusions 101 have through holes to allow the tungsten paste heating layer to communicate with the tungsten paste heating circuit 3. The tungsten paste heating layer is also part of the tungsten paste heating circuit 3. The upper side of the upper ceramic layer 1 is provided with an outer ceramic layer 4. The upper side of the outer ceramic layer 4 has a plurality of second spherical protrusions 401 integrally formed on its upper side. The lower side of the outer ceramic layer 4 is provided with a plurality of spherical grooves 402. The number of first spherical protrusions 101, second spherical protrusions 401, and spherical grooves 402 are the same, and their positions are vertically corresponding. The first spherical protrusions 101 are in contact with the inner side of the spherical grooves 402.

[0018] Two electrode holes are formed through the upper ceramic layer 1. The two electrode holes are located at the two ends of the tungsten paste heating circuit 3, and an energizing component connected to the tungsten paste heating circuit 3 is provided in the electrode holes.

[0019] In this embodiment, the power-conducting component includes an electrode plate 5 disposed in an electrode hole and a nickel wire 6 disposed on the electrode plate 5. The end of the nickel wire 6 away from the electrode plate 5 is connected to an external power source, and the electrode plate 5 is attached to the end of the tungsten paste heating circuit 3.

[0020] In this embodiment, the nickel wire conductor 6 is covered with a Teflon sleeve 7.

[0021] In this embodiment, the upper ceramic layer 1, the lower ceramic layer 2, and the outer ceramic layer 4 are all 96% alumina ceramic.

[0022] During the manufacturing process, the workers print the tungsten paste heating circuit 3 onto the opposite sides of the upper and lower ceramic plates. Then, the workers print a layer of tungsten paste heating layer on the outer surface of the first spherical protrusion 101. Under the action of the through hole, the tungsten paste heating layer and the two ends of the tungsten paste heating circuit 3 are connected. After the printing is completed, the workers place the outer ceramic layer 4 on the upper side of the upper ceramic plate and fix the upper ceramic plate, the lower ceramic plate and the outer ceramic layer 4 together by high-temperature sintering.
